AUTOMATIC DEVICE FOR ENGAGING ENDS .OF TRAVELlNG MUSIC-SHEETS.

SPECIFICATION forming part of Letters Patent No. 664,604, dated December25, 1906.

Application filed February 8, 1898. Serial No. 669,605. (No 'model.)

is a vertical transverse section of a windingroller, showing thelocking-hook in the act of engaging with the end of the travelingmusicsheet. shown in Fig. 2 with a portion of the traveling music-sheetcut away to disclose the engaging device beneath. Fig. 4 is a vertical.

section of the traveling m usic-sheet roller, the music-sheet tracker,and the winding-roller, showing my automatic locking-hook engaged withthe traveling music-sheet and looking it to the winding-roller. Fig. 5is a front elevation of the parts shown in Fig. 4 with a portion cutaway to disclose the music-sheet tracker. Fig. 6 is one form ofequivalent of my locking hook or lever, as shown in Fig. 1.

My invention relates to that class of musical instruments whosesound-prod ucing mechanism is operated by means of a perforated paperstrip or its equivalent, commonly termed a traveling music-sheet; and itparticularly relates to the means for connecting such travelingmusic-sheet to the winding-roller and disconnecting it therefrom.Heretofore the means for connecting the traveling music-sheet to thewinding-roller and discon necting it therefrom has been imperfect andinconvenient, requiring careful manipulation to properly efiect theengagement and disengagement of the sheet. Furthermore, the old devicesare defective, for the reason that the sheet is liable to becomeaccidentally disengaged from the winding-roller.

The object of my device is to remedy these disadvantages.

To that end my invention consists in certain features of constructionand combination hereinafter described, and pointed out in the claims.

Fig. 3 is a front elevation of the parts In the accompanying drawings,Ais a music-sheet roller or supply-roll; B, a traveling music-sheetprovided at its free end with a ring, eye, or similar device; C, amusic-sheet tracker, and E a winding-roller having a groove or slot G,of such shape as may be desired, cut or sunk in the face thereof.

The general operation of themusic-sheet roller or supply roll A, thetraveling musicsheet B, the music-sheet tracker O, and thewinding-roller E is the same as that now commonly used and old in theart.

Heretofore it has been necessary for the operator of such an instrumentwhen it was desired to attach a traveling music-sheet to thewinding-roller or disconnect it therefrom to perform the operation byhand, such connection or disconnection, as the case may be, beingrespectively accomplished by passing a hook, eye, ring, or otherequivalent over a pin, hook, or similar engaging device or removing thesame therefrom. This manual operation is inconvenient and sometimesdiffi cult. I therefore have substituted in place of the hook, pin, orsimilar engaging contrivance now in common use a locking hook or leverwhich automatically engages the traveling music-sheet and causes it tobe smoothly and properly wound or drawn around the winding-roller.

In Fig. 1, H is a base-plate, at one end of which suitable means isprovided for fastening it in 'place to the winding-roller E--forexample, the small perforations 0, through which pins, screws, or thelike may be passed. At the other end of the plate H is a lug or lugs J,having near its or their farther end or ends a perforation orperforations L, through which any suitable pin or other device may bepassed to serve as a pivot for the locking hook or lever K. The resultis that when the music-sheet B is brought into the proper position andthe roller E is turned in the winding direction the end K of the hook orlever K catches in the ring D and forces the latter backward into therecess M and against the shoulder M,which being upon the opposite sideof the fulcrum causes the projecting part K to be withdrawn into thegroove G of the roller E, where it will not interfere with the properrolling of the musicsheet B upon the roller E. The continued rotation ofthe roller E winds the music-sheet B smoothly and evenly around itsperiphery. To disengage the music-sheet from the winding-roller, it isonly necessary to reverse the movement of the roller.

It will be observed that the draft of the 7 ring D upon the shoulder Mof the hook 1 lever K has the effect to lock the latter securely in thegroove Gr while the winding operation is going on. It will also beobserved that the periphery of the roller E is recessed to accommodatethe weighted end K of the hook or lever K and to limit the outward throwof its tapered arm K; Instead of the weight it is obvious that a cam,spring, or

othe q a e m n may b emp er f projecting the arm K of the hook or leverK into the path of the music-sheet B and that the iorm of the device maybe greatly varied without departing from the principle of theinvention.for example, the form shown in Fig. 6.

Wh le the ngaging op on ha been hereinbefore described as automatic, itmay also readily and conveniently be performed by hand, it only beingneQBSSary that the operator should bring the winding-roller and the music-sheet into proper position and slip the ng D ever t a m K, re pen hfurther rotation of the roller in the winding direction willautomatically lock the music: sheet to the same.

Having thus desoribed the principle of my invention and one way in whichit I 3) be carried into practice and illustrated in the drawings, Fig.6, one form of an equivalent of my locking hook or lever, what I claimas new, and desire to secure by Letters Patent, 1s-- 1. In a musicalinstrument of the characterdescribed,a winding-roller having a groove orrecess therein, an engaging member fulcrumed in said groove or recess,an engaging part of said member which projects beyond or out of saidgroove or recess, when the winding-roller is at rest or rotating in adirection opposite to that of Winding and an abutment or extensionalsoon the engaging member operated by the end of the musicsheet when thelatter is caught by the projecting part of the engaging member.

2- 1 a musical ins rumen of the kind scribed, a hook, or its equivalent,fulcrumed upon the winding-roller, and provided with an engaging end, orarm, K, and at the op posite end therefrom an end, or arm, K adaptedthrough its gravity or other equivalent means, to cause the engagingarm, K, WheIl in its ma p sitieh, t pretr de h y hd t e pe ip ry f thendin -r l r he purp s h ein e ort su ant y as described.
